DSC-F828 Colour fringing Important Product Information

February 9, 2004

Q1: Colour fringing may be observed in images recorded by the DSC-F828 digital camera. What is this phenomenon?

A1:Colour fringing may occur when shooting subjects with high contrast or extreme variation in light levels. It is seen as a color "fringe" in the image where bright light is immediately adjacent to dark. Colour fringing results from the difference of refractive index caused by different light wavelengths as they pass through the lens.

Q2: Under what conditions is color fringing more likely to occur?

A2: This phenomenon may be more likely to occur when shooting strongly backlit subjects or reflective surfaces with flash while using wide aperture. Under these conditions, colour fringing is normal characteristic of images recorded by digital camera technology.

Q3: How can the likelihood of colour fringing be reduced ?

A3: When shooting strongly backlit subjects or reflective surfaces with flash, the likelihood of colour fringing may be reduced by selecting a narrower aperture (f4-f8, for instance) or avoiding such conditions. The likelihood of this phenomenon may also be reduced by reducing the overall exposure level.
